To determine the scale factor, we need to compare the corresponding sides of the two triangles. Let's select a side from the original triangle on the left and its corresponding side on the copy on the right.
Let's choose the side that has a length of 4 centimeters on the original triangle. Looking at the copy, we can see that the corresponding side has a length of 8 centimeters.
To find the scale factor, we divide the length of the corresponding side on the copy (8 centimeters) by the length of the corresponding side on the original (4 centimeters):
Scale factor = length of side on copy / length of side on original
Scale factor = 8 cm / 4 cm
Scale factor = 2
Therefore, Randy used a scale factor of 2 to create the copy on the right from the original on the left.
Randy draws these two triangles with links given in centimeters. What scale factor does she used to create the copy on the right from the original on the left?
